Nena Farrell Gear Mar 3, 2026 8:31 AM Review: Shark PowerDetect UV Reveal The UV light built into Shark’s newest robot vacuum is on a quest to embarrass me with how many stains it’s spotted. Save this story Save this story Rating: 8 /10 Open rating explainer WIRED Does a great job both vacuuming and mopping. Stain Detect is handy and pretty consistently spots stains. Works fairly fast.
